The objective of the research was to determine the effect of frequency and duration of ultrasonication on the physical and chemical characteristics of cold brew coffee. This research was conducted at the Agricultural Product Processing Laboratory and Agricultural Product Chemical Laboratory, Faculty of Agriculture, Sriwijaya University, Indralaya, South Sumatra. This study used a Factorial Completely Randomized Design (RALF) with 2 factors. The first factor was frequency of ultrasonication (A) consisting of 20 and 40 KHz and the second factor was duration of ultrasonication (B) consisting of 5, 10 and 15 minutes. The parameters included physical characteristics (extract content and brewing color) and chemical characteristics (caffeine content and pH). The results showed that the effect of ultrasound frequency had a significant effect on extract content and pH but has no significant effect on brewing color (lightness, chroma and hue). The duration of ultrasonication had a significant effect on the extract content but has no significant effect on extract content and brewing color (Lightness, Chroma and Hue). Meanwhile, the interaction between two factors had a significant effect on the extract content and pH. The best treatment was A1B1 (20 KHz, 5 minutes) treatment with 20.52% extract content, pH of 5.26, caffeine content 1534.04 ppm and brewing color (lightness 29.17%, chroma 11.47% hue 183.33 0).
